One thing I plan to ask at my next session is "Do you want me to do the accent?"
To explain: last year, I ran the Ravenloft season of AL modules for my group. I didn't do the Barovian accent because I figured everyone in the story was speaking the same language.
However, my players have a long history with Ravenloft, and whenever they quote past games, they always do the accent. We're about to start Curse of Strahd, so if they feel like the accent would improve the experience for them, I'll do it. Even if it means pretty much all of us end up sounding like a tableful of Bela Lugosis.
